Why is SB not compatible with Specialized bikes if it is a simple divider?

Jiří Voldán (Sales Manager)Administrator |

Hi Brian. We just got the Specialized eBike and currently updating SpeedBox for Brose. I think the SpeedBox for Specialized will be available in 2 weeks :) I know it's not an answer for your question but I am not a developer. My colleague is. All I know is that the motor needs more power than standard Brose. We had to add some component on the motherboard because of it. Please contact me in 2 weeks ;)
